In ksh, you can do this:

Code:
set -A find_use `ccm folder -fu -u -f "%name"-"%version" ${FOLDER_ID}`
 
echo ${find_use[0]}, ${find_use[1]}, ${find_use[*]}, ${#find_use}, etc...

Thanks quirkasaurus, though I'm not entirely sure if that's what I'm wanting.

For each result returned by FIND_USE=`ccm folder -fu -u -f "%name"-"%version" ${FOLDER_ID}` I need to be able to perform a command upon.

i.e. I want to run a command which will use agriculture-stst as a variable and then run again and use agriulture-uat (and again if there has been anything else returned by the initial FIND_USE= ...

Am I needing to use some sort of "while" loop? I'm a bit of novice at this still..

Many thanks
Glyn

prev

prev(1) 						      General Commands Manual							   prev(1)

NAME

       prev - show the previous message (only available within the message handling system, mh)

SYNOPSIS

       prev [+folder] [-[no]header] [-help] [-showproc program] [-noshowproc] [options to showproc]

OPTIONS

       Displays  a  one-line  header before the message. The header consists of the name of the folder and the message number. This is the default
       behavior. It can be suppressed with the -noheader option.  Prints a list of the valid options to this command.	Specifies  an  alternative
       program	to list messages. The default is to use the program defined by the showproc: entry in the file. As with show, you can give options
       to the showproc program at the command line. These are passed directly to showproc by prev.

       The defaults for this command are:

       +folder defaults to the current folder -header

DESCRIPTION

       The prev command displays the previous message in the current folder.  The previous message is the one before the current  message  in  the
       folder.	The message that is shown becomes the current message.

       You  can  specify  a  folder other than the current folder by using the +folder argument. If you specify a folder, that becomes the current
       folder.

RESTRICTIONS

       The prev command is really a link to the show program. As a result, if you make a link to prev and that link is not called prev, your  link
       will act like show instead. To avoid this, add a profile-entry for the link to your MH profile and add the argument prev to the entry.

PROFILE COMPONENTS

       Path: To determine your Mail directory

       showproc: Program to show the message

EXAMPLES

       The command in the following example displays the previous message in the folder +copylog: $ prev +copylog

FILES

       The user profile.
